That prototype works fine for my needs, which are simple:  I was looking
for a way to have the 'invokeFactory' bit land on a view, rather than
doing the actual work.  The views I am using there are not
schema-generated add forms, but I don't know any reason why such a view
wouldn't work.

My own view classes do have some grotty bits in them which are emulating
the "post-creation" stuff (setting portal_type, notifying workflow and
the catalog, etc.), and hence would get much simpler with the "added"
events stuff you describe.
